WooCommerce: Add Column to Orders Table @ WP Dashboard

The WooCommerce Orders Table, which can be found under WP Dashboard > WooCommerce > Orders, provides us with 7 default columns: Order – Date – Status – Billing – Ship to – Total – Actions. This is used by shop managers to have an overview of all orders, before eventually clicking on a specific one.

So the question is: how can we display additional columns to that same orders table, so that we can immediately visualize an order custom field, a specific product contained in the order, or anything order-related that can be “calculated” once we have access to the $order variable?
